Our invention consists of an arrangementof long levers and springs toobtain the pressure on the pressure-roller by light and sensitivesprings, which are better adapted for obtaining a wide range of movementthan the strong heavy springs which are necessary when short levers areused or none at all.

Figure 1 is a sectional elevation of our improved machine, taken on theline as w of Fig. 2. Fig. 2 is a transverse section taken on the line asa: of Fig. 1. p

A is the lower mangling and wringing roller, which is mounted in fixedbearings, so that the top runs flush with the top of the table B. O isthe upper roller, with its journals arranged in the slotted housings D,so as to rise and fall. Its shaft is connected by caps E, stirrups F,and adjusting screws G, with the short arms of levers H projectingthrough the frame at the ends near the bottom from the pivots I, whilethe long arms extend to the center or thereabout, where they areprovided with light coiled springs K on vertical rods L, pivoted to thelevers to rise and fall with them to control the springs,

which rest on the bottom rail M of the frame, to produce the pressure onthe roller 0. The

tension is varied by the adjusting-screws G. p

N is the endless carrier, ot'tcanvas or other suitable substance,passing between the rollers A 0 over a guide-roller O at each end of thetable and under it, and the roller A to draw the clothes along the tableand between i claim as new and desire to secure by Letters Patent i vThe combination of the springs K, levers H, adjusting screws G, andstirrups F, with the pressure-roller 0, substantially as specified.
